Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to an anti-flying material mechanism for a pipe fitting cutting device. Background Art

[0002] Cutting equipment is applied in different fields, and the items to be cut are also different. Taking the aluminum pipe in cutting equipment as an example, the existing aluminum bar cutting machine is provided with a tunnel-type operation table, a material receiving hopper for receiving aluminum bars, and a conveyor. The aluminum bar is threaded through the operation table and cut by a saw blade on the cutting machine. The material receiving hopper is arranged below the outlet of the operation table, and the cut short aluminum bar is pushed out of the operation table by a push rod and received by the material receiving hopper. One end of the conveying mechanism is connected to the material receiving hopper, and its conveying direction is perpendicular to the pushing direction of the aluminum bar. After the material receiving hopper receives the short aluminum bar, it transfers the short aluminum bar to the conveying mechanism and transports it to the next process through the conveying mechanism.

[0003] Publication No. CN116921757A discloses an automatic pipe cutting machine. It includes a pipe cutting component, a positioning device, a moving device, a control system, a frame, a conveyor belt, and a pipe feeding component. A plurality of pipe cutting components are displaced along the frame through the moving device. A plurality of magnetic positioning cutting positions are arranged on the frame. The control system synchronously controls the plurality of pipe cutting components to move to the corresponding magnetic positioning cutting positions. An electromagnet is arranged at the bottom end of the pipe cutting component and magnetically adsorbed to the magnetic positioning cutting position. A pipe cutting position is arranged on the pipe cutting component, and the supporting member on the pipe cutting position is separable. After separation, the supporting member transfers the pipe body to the conveyor belt. The automatic pipe cutting machine realizes precise cutting, custom segmented length cutting, and high-efficiency cutting and output, with a high degree of automation. An electromagnet is arranged on the base for magnetic adsorption positioning with the magnet absorbing plate on the frame; the driving mechanism and the guiding mechanism cooperate to stably move the base to the corresponding positioning cutting point.

[0004] However, this pipe cutting machine does not have a certain limit on the pipe fittings, and the pipe fittings are prone to flying materials after cutting, so that the pipe fittings cannot fall well on the conveyor belt. Therefore, it is necessary to design an anti-flying material mechanism to solve this problem. Content of the Utility Model

[0005] Other features and advantages of the present utility model will be described in the following specification, and will be partially obvious from the specification, or understood by implementing the present utility model. The objectives and other advantages of the present utility model can be achieved and obtained through the structures specifically pointed out in the specification and other specification drawings.

[0006] The purpose of the present utility model is to overcome the above deficiencies and provide an anti-flying material mechanism for a pipe fitting cutting device.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a flying material prevention mechanism of a pipe cutting device, comprising a frame, a saw blade, a fixed wheel and a movable wheel, the frame being rotatably connected to a pressure rod through a connecting mechanism, one end of the pressure rod extending between the fixed wheel and the movable wheel, and the frame being provided with a force-applying mechanism for enabling the pressure rod to apply pressure to the pipe.

[0008] By adopting the above technical solution, during the cutting process of the cutting device, the pipe is located below the saw blade, and the pipe is located in the groove formed between the fixed wheel and the movable wheel. The force-applying mechanism can be used to make the pressure rod always exert a downward pressure on the pipe, so that the pipe can be pressed tightly against the fixed wheel and the movable wheel. Therefore, after the saw blade completes the cutting, the pipe will not fly due to the cutting force, but will fall onto the conveyor belt after the movable wheel retreats, thereby achieving the effect of preventing flying materials.

[0009] Preferably, the connection mechanism includes a connection plate, the connection plate is fixedly connected to the frame via a fixing mechanism, and the pressure rod is rotatably connected to the connection plate via a rotating mechanism. The utility model uses the connection plate as a supporting component of the pressure rod, so that the pressure rod can be connected to the frame and can avoid interference with other components through the structure of the connection plate.

[0010] Preferably, the fixing mechanism includes two fixing bolts, the two fixing bolts penetrate the connecting plate, and the two fixing bolts are threadedly connected to the frame. The utility model can press the connecting plate onto the frame to achieve fixation through the two fixing bolts, and also position the connecting plate by using the two fixing bolts.

[0011] Preferably, the rotation mechanism includes a shaft sleeve and a clamping bolt, the pressure rod is rotatably connected to the shaft sleeve, the clamping bolt passes through the shaft sleeve, and the clamping bolt is threadedly connected to the connecting plate. The utility model can use the clamping bolt to clamp the shaft sleeve on the connecting plate, and then by arranging the pressure rod sleeve on the shaft sleeve, the rotation connection between the pressure rod and the connecting plate can be achieved, and the shaft sleeve can reduce the wear of the pressure rod when it rotates.

[0012] Preferably, the shaft sleeve is provided with a spacer, and the spacer is arranged between the pressure rod and the connecting plate. The utility model can separate the pressure rod from the connecting plate by using the spacer, so that the pressure rod will not rub against the connecting plate when rotating, and also plays a positioning role for the pressure rod, reducing its axial shaking.

[0013] Preferably, the pressure rod abuts against the pipe through a roller, and the roller is rotatably connected to the pressure rod. The utility model uses a roller instead of a pressure rod to contact the pipe, which can reduce the wear between the pipe and the pressure rod, thereby preventing the pipe from being scratched and affecting the appearance.

[0014] Preferably, the force applying mechanism includes a tension spring. One end of the tension spring is rotatably connected to the pressure rod through a mounting mechanism, and the other end of the tension spring is fixedly connected to the frame. In the present utility model, the mounting mechanism is used to connect one end of the tension spring to the middle of the pressure rod, and the other end is fixed to the frame, so that the tension spring can apply an elastic force to the pressure rod with the frame as a support, thereby enabling the pressure rod to maintain a state of tightly pressing the pipe fitting.

[0015] Preferably, the mounting mechanism includes a connecting bolt and a washer. The connecting bolt is threadedly connected to the pressure rod, the washer is sleeved on the connecting bolt, the hook of the tension spring is hooked on the connecting bolt, and the hook of the tension spring is located between the washer and the connecting bolt. In the present utility model, the threaded connection between the connecting bolt and the pressure rod enables the hook of the tension spring to have a place to be mounted, and the washer can limit the axial position of the hook of the tension spring.

[0016] Preferably, the connecting plate is fixedly connected with a limiting plate for limiting the rotation range of the pressure rod. In the present utility model, the limiting plate can limit the rotation range of the pressure rod, so that it will not rotate excessively when the pipe fitting is separated, thereby affecting the next processing.

[0017] In summary, the beneficial effects of the present utility model are as follows:

[0018] 1. The force applying mechanism can enable the pressure rod to always apply a downward pressure to the pipe fitting, so that the pipe fitting can be tightly pressed on the fixed wheel and the movable wheel. After the saw blade completes the cutting, the pipe fitting will not fly off under the action of the cutting force, but will fall onto the conveyor belt only after the movable wheel retracts, thereby achieving the effect of preventing flying materials.

[0019] 2. The limiting plate can limit the rotation range of the pressure rod, so that it will not rotate excessively when the pipe fitting is separated, thereby affecting the next processing.

It should be understood that the specific implementation manners described herein are only used to explain the present invention, but not to limit the present invention.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0033] As Figure 1-2 shown, a flying material prevention mechanism of a pipe fitting cutting device includes a frame 1, a saw blade 2, a fixed wheel 3, and a movable wheel 4. The frame 1 is rotatably connected with a pressure lever 5 through a connection mechanism. One end of the pressure lever 5 extends between the fixed wheel 3 and the movable wheel 4, and the frame 1 is provided with a force application mechanism for enabling the pressure lever 5 to apply pressure to the pipe fitting.

[0034] By adopting the above technical solution, during the cutting process of the cutting device, the pipe fitting is located below the saw blade 2, and the pipe fitting is located in the groove formed between the fixed wheel 3 and the movable wheel 4. The force application mechanism can be used to make the pressure lever 5 always apply a downward pressure to the pipe fitting, so that the pipe fitting can be pressed tightly on the fixed wheel 3 and the movable wheel 4. Thus, after the saw blade 2 completes the cutting, the pipe fitting will not fly off under the action of the cutting force, but will only fall onto the conveyor belt after the movable wheel 4 retracts, thereby achieving the effect of preventing flying materials.

[0035] The connection mechanism includes a connecting plate 6. The connecting plate 6 is fixedly connected with the frame 1 through a fixing mechanism, and the pressure lever 5 is rotatably connected with the connecting plate 6 through a rotating mechanism. Using the connecting plate 6 as the supporting component of the pressure lever 5 enables the pressure lever 5 to be connected to the frame 1 and also prevents interference with other components due to the structure of the connecting plate 6.

[0036] The fixing mechanism includes two fixing bolts 7. The two fixing bolts 7 penetrate through the connecting plate 6, and the two fixing bolts 7 are threadedly connected to the machine frame 1. Through the two fixing bolts 7, the connecting plate 6 can be pressed tightly on the machine frame 1 to achieve fixation, and at the same time, the connecting plate 6 is positioned by using the two fixing bolts 7.

[0037] The rotating mechanism includes a bushing 8 and a pressing bolt 9. The pressing rod 5 is rotatably connected to the bushing 8. The pressing bolt 9 penetrates through the bushing 8, and the pressing bolt 9 is threadedly connected to the connecting plate 6. By using the pressing bolt 9, the bushing 8 can be pressed tightly on the connecting plate 6. Then, by sleeving the pressing rod 5 on the bushing 8, the rotational connection between the pressing rod 5 and the connecting plate 6 can be achieved. The wear during the rotation of the pressing rod 5 can be reduced through the bushing 8.

[0038] A spacer sleeve 10 is sleeved on the bushing 8. The spacer sleeve 10 is arranged between the pressing rod 5 and the connecting plate 6. By using the spacer sleeve 10, the pressing rod 5 can be separated from the connecting plate 6, so that the pressing rod 5 will not rub against the connecting plate 6 when rotating. At the same time, the spacer sleeve 10 also plays a role in positioning the pressing rod 5 and reducing its axial wobbling.

[0039] The pressing rod 5 abuts against the pipe fitting through a roller 11. The roller 11 is rotatably connected to the pressing rod 5. By using the roller 11 to contact the pipe fitting instead of the pressing rod 5, the wear between the pipe fitting and the pressing rod 5 can be reduced, thereby preventing the pipe fitting from being scratched and affecting its appearance.

[0040] The force - applying mechanism includes a tension spring 12. One end of the tension spring 12 is rotatably connected to the pressing rod 5 through a mounting mechanism, and the other end of the tension spring 12 is fixedly connected to the machine frame 1. By using the mounting mechanism, one end of the tension spring 12 is connected to the middle of the pressing rod 5, and the other end is fixed to the machine frame 1, so that the tension spring 12 can apply an elastic force to the pressing rod 5 with the machine frame 1 as a support, thereby enabling the pressing rod 5 to maintain a state of pressing tightly on the pipe fitting.

[0041] The mounting mechanism includes a connecting bolt 13 and a washer 14. The connecting bolt 13 is threadedly connected to the pressing rod 5. The washer 14 is sleeved on the connecting bolt 13. The hook of the tension spring 12 is hooked on the connecting bolt 13, and the hook of the tension spring 12 is located between the washer 14 and the connecting bolt 13. By using the threaded connection between the connecting bolt 13 and the pressing rod 5, a mounting place for the hook of the tension spring 12 can be provided, and the washer 14 can limit the axial position of the hook of the tension spring 12.

[0042] The connecting plate 6 is fixedly connected with a limiting plate 15 for restricting the rotation range of the pressing rod 5. By using the limiting plate 15, the rotation range of the pressing rod 5 can be restricted, so that it will not rotate excessively when the pipe fitting is separated, thus affecting the next processing.

[0043] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited by the specific embodiments disclosed below.
